When I let the muscovies out this morning, i noticed blood on a few of them. After inspection, it's one bird with a bloody feather. It looks like the wing is bruised with the feather pin having received the brunt of the trauma. I'm not sure if something tried to grab her out of the pen and she struggled, or if she got herself caught somewhere and pulled herself out. The question is, does she need to be isolated? The ducks are running with turkeys of similar age and meat chickens. They free range.
